Reasons you might have a B Belly: a few other factors...

I would like to start this blog post with, I am not a doctor and this is not to treat or diagnose any medical condition, Im simply sharing information I have gathered over the past year about this subject and sharing it with you. Always seek your doctor when talking about medical conditions you might be concerned about.

Body diversity is a beautiful aspect of humanity, and understanding the factors that contribute to various body shapes can help foster acceptance and compassion for yourself and for others. Obviously the body shape we are going to focus on today is a B Belly—a term used to describe an abdomen that resembles the letter "B" when viewed from the side. While there is no singular cause for a B Belly, several factors can contribute to its development. We have already covered PCOS and Insulin Resistance, but in todays post, we will explore a few other reasons why someone might develop a B Belly, shedding light on the complexity of body composition and individual differences.


Genetic factors play a significant role in determining body shape and fat distribution. Some individuals may have a genetic predisposition to carry excess weight around their midsection, leading to the development of a B Belly. Genetic variations can influence factors such as metabolism, hormone regulation, and fat storage patterns. If you look at every single woman in my family, we all have B Bellies. From me at a size 22 down to my daughter who is a size 4/6, so it doesn't just affect plus size women.

B Bellies can happen to people of all sizes!!

Hormonal Imbalances:

Hormones can influence body fat distribution, particularly around the abdominal area. Hormonal imbalances, such as those seen in conditions like polycystic ovary syndrome (PCOS), which we cover in this blog post, or adrenal disorders, may contribute to the development of a B Belly. These imbalances can affect how fat is stored and distributed in the body.

Dietary Habits:

I don't personally assign morality to food. I don't believe any food is "bad" or "good", but we do know that our bodies need certain things to survive and other things to make us feel good! Eating patterns that include daily intake of highly processed foods, refined carbohydrates, and added sugars, can contribute to accumulation of visceral fat around the midsection. Excessive calorie intake without adequate nutritional balance can lead to increased fat storage in the abdominal region also, so make sure you indulge every once in a while but maintain balance in your diet! All things in moderation!

Sedentary Lifestyle:

A lack of physical activity and a sedentary lifestyle can contribute to the development of a B Belly. Regular exercise helps increase muscle tone, and improves overall body composition. Insufficient physical activity can lead to a decrease in muscle mass and an increase in fat accumulation, particularly in the abdominal area. Find ways to joyfully move your body without the goal of weight loss! Go for a walk, take a dance class, enjoy some stretching - whatever feels good to move your body! Joyful movement works on your mental health as well! Remember that exercise is NOT a punishment because of what you ate!!

Stress and Cortisol:

Chronic stress triggers the release of the hormone cortisol, which can contribute to weight gain and fat storage, particularly in the abdominal region. High cortisol levels are associated with increased appetite, cravings for high-calorie foods, and the accumulation of visceral fat—the fat that surrounds internal organs and contributes to a B Belly appearance. Remember that taking care of your mental health is just as important as your physical health! If you need some reminders of why you're amazing, check out these cards!!

Age and Hormonal Changes:

As individuals age, hormonal changes occur in the body, which can influence body composition and fat distribution. Hormonal shifts, particularly in menopause for women, can lead to an increase in abdominal fat storage and the development of a B Belly.

Lack of Sleep:

Inadequate sleep or poor sleep quality can disrupt hormonal balance and metabolism, leading to an increased likelihood of developing a B Belly. Sleep deprivation affects appetite-regulating hormones, such as leptin and ghrelin, which can lead to overeating and fat storage.

Medical Conditions and Medications:

Certain medical conditions, such as Cushing's syndrome or hypothyroidism, can cause abdominal fat accumulation. Additionally, certain medications, such as corticosteroids or some antidepressants, may contribute to a B Belly appearance as a side effect.

Pregnancy and/or C-Sections:

As we all know, pregnancy can drastically change a woman's body. As the baby grows, the uterus expands, stretching the abdominal muscles and skin. During pregnancy, hormonal changes, including increased levels of estrogen and progesterone, can influence fat distribution and cause weight gain, especially in the abdominal area.

Lot's of women experience B Bellies without ever having gone through pregnancy, others only develop one during pregnancy and then return to their previous shape after, and some women develop a B Belly much lower in their belly due to a C section scar, so their indentation of the B closer to their pelvis than their belly button. A B belly can also form during or after a pregnancy because of scar tissue development or diastasis recti where your abdominal muscles separate and can only be repaired surgically. I'll be posting an entire blog post about B Bellies and pregnancy soon!

The development of a B Belly can be influenced by various factors, some not even mentioned here. It is important to recognize that body shapes and sizes are diverse and unique to each individual. Embracing body neutrality and focusing on overall health and well-being rather than conforming to societal ideals is key. By understanding the reasons behind the development of a B Belly, we can foster acceptance, compassion, and support for individuals with diverse body shapes. Remember, our bodies are incredible, and so are we!
